Waraksa was arrested in July 2010 -- more than 23 years after the crime -- in connection with the deaths of Orie “Harold” Weeks, 59, and his wife, Assunta, 57, who were found dead after a fire at their home on Oct. 7, 1986.

Waraksa, a member of the Warehouse Point Volunteer Fire Department at the time of the fire, was charged with arson murder after an investigation by East Windsor police and the state cold case unit.

He was already in prison at the time of the arrest, serving a five-year sentence issued in 2007 for sexually assaulting five boys.
